Cosine is one of the three part for trigonometry.

You have sin, cos, and tan.

You can easily do this by understanding SOH CAH TOA.

Sin = OPPO. over HYPOTENUSE
Cos = ADJACENT over HYPOTENUSE
Tan = OPPO. over ADJACENT

I hope this helps!

ella [17]

Answer: if you have infinity points, which i will asume are the events, they cant have the same probability because then the probability will not be normalized, because in graph of prob vs variable, you will se infinite area under the curve if the probability is constant.

And yes, can all points have positive probability of occurring, but besides you medium value (the bell for example) you will see an asintotic decrease to the zero.
